This kind of descriptive work won’t make the front page of Nature, but it’s essential for protecting lesser-known species.
Science isn’t always flashy, but it matters!
This study, led by @ird-fr.bsky.social and @birdnewcaledonia.bsky.social, will provide essential information for their conservation

But the species is in trouble:
🛠️ Habitat loss from mining
🐀 Predation by rats & cats
🎣 Bycatch risk due to scavenging behavior
Our study shows breeding success drops where predators are present.

🥚Once mature, they return to their birthplace to lay a single egg in a burrow.
Unlike most other species, they breed year-round, reducing interspecific competition.
Both parents take turns going to sea, traveling thousands of kilometers to bring food back to their chick.

🔍 During my PhD in New Caledonia, we surveyed dozens of islets and hiked into remote mountain forests to find the burrows where they nested 🏝️⛰️ searching for a needle in a haystack!
🎊But we eventually found what may be the largest known colony of this species. A major step for its conservation !

Very beautiful graphs and impressive results!
As you partially explain the changes in body mass by an increase in insect abundance, could the absence of a long-term relationship be due to a lack of correlation between temperature and insect abundance over the long term?
